...was listed in the catalogs of the oriental manuscripts at the University Library of Leiden,¹ it was thought that this might be our Book of Causes original: "de causis".
L. Zunz was the first to voice this suspicion,² doing so with regard to and by citing that Hebrew translation. M. Steinschneider repeated it, following the aforementioned remark by Jourdain.³ Haneberg subsequently examined the manuscript itself and confirmed that its content was indeed the Book of Causes (see the Introduction).
This manuscript was lent to me for copying in the year 1873 through the kind mediation of Professor Dr. M. J. de Goeje in Leiden.
This same manuscript was brought from the Orient by the famous Arabic scholar Jakob Golius (who died in 1667) and is listed as number 209 among the Golius manuscripts.⁴ It consists of 29 leaves in a small quarto format A book size where each sheet is folded twice, creating four leaves; typically about 9 by 12 inches and is written in large, regular, flowing strokes. But unfortunately, it is no longer in its original, pristine condition. Later hands have not only provided the margins with several glosses explanatory or marginal notes added by later readers but have also incorporated changes into the text itself; through these corrections as well as erasures areas where the original ink was scraped off the parchment or paper to allow for rewriting in several places, the handwriting of the original scribe has been made unrecognizable.

In a later passage which Haneberg overlooked, column 1404, Steinschneider was able to testify "from personal inspection" original: "ex autopsia" that the earlier suspicion was correct.
